I have an older Model 56 (I guess that's redundant), and would like to know if anyone has advice for sighting it in. I've put about 30 - 40 rounds through it at the range, and it's reasonably accurate at short distance (~15 yards), but i would like to sight it in at 25 yards (standard for 22LR?). I know that for the larger calibers they make laser bore-sights that you can chamber like a regular round, but I have not seen one for 22LR. I do have a rifle vise and a spotting scope. Any advice would be appreciated.
